After a little more research null is a valid value put it's unusual to encounter it in a dictionary entry. I've updated the Lexer to handle null and return the equivalent null Java value.

The root of the problem is related to parsing some unexpected or malformed inline image parameters. Need to work our a strategy for our lexer to correctly handle this unusual case.
